- Permits operation in night mode with Singlecontroller 7091. Attached to the connecting port, the night-mode operation is activated automatically. The photo-electric cell can be used to lower the pumping power during the night. Like in a reef, small animals and plankton can rise in the aquarium to take the habitat of diurnal animals.
- By placing the photo-electric cell in the beam area of the aquarium lamp, the pulse operation of the pump is also interrupted when the lamp is switched off. The pump will then continue operation at the performance set on the "Power 2" knob. The LED indicator beside the knob will light up red. When the light is switched on again, the selected pulse operation of the pump will start.
- Note: Keep a minimum distance of 30 cm between the cell and any high intensity discharge (HID) lamps as damage caused by light and heat from these types of lamps is unavoidable.
